Below is the typical activation announcement from WX4NHC Assistant Coordinator, Julio Ripoll-WD4R and WX4NHC Coordinator John McHugh-K4AG:


WX4NHC, the Amateur Radio station at the National Hurricane Center in Miami, will be activating it's HF and EchoLink/IRLP station on Wednesday June 30th, 2010 at 8 AM EST/7 PM CST (1200z).


We request all land based stations as well as ships at sea in the areas affected to send us weather data (measured or estimated) and damage reports.

If you are in the affected area and normally monitor on a local Net on VHF, 40 or 80 meters, we would appreciate your checking into the HWN NET or EchoLink/IRLP Net once per Hour to receive the latest Hurricane Advisories and to report your local conditions.

Please do not venture outside during the hurricane to gather weather data.

Your safety is the first priority.

There are many constantly changing atmospheric variables that affect the storm's track and strength.

Please refer to the National Hurricane Center Advisories for official information. www.nhc.noaa.gov

WX4NHC will be monitoring the Hurricane Watch Net www.hwn.org on 14.325 MHz.

Secondary HF frequencies will be 7.268 MHz and 3.950 MHz +/- QRM, should we loose propagation on 20 meters.

EchoLink "WX-Talk" Conference Room and IRLP node 9219 will also be monitored. www.voipwx.net

WX4NHC will also monitor CWOP, APRS and MADIS/MESONET Automated weather stations in the affected area.

Surface Reports using our On-line Hurricane Report form will be monitored.

Amateur Weather Enthusiasts and ON-NHC Volunteers may report directly to WX4NHC on-line.


ON-NHC Volunteers are both Ham Radio Operators and Non-Ham weather observers that use their own weather instruments to submit "Surface Reports" directly to NHC over the Internet via the WX4NHC on-line report form. These "Surface Reports" are very important as they give Hurricane Specialists at NHC a better idea of what is actually happening on the ground level during the storm.

The WX4NHC Group continues to expand its efforts to increase the quantity and quality of surface reports to include many different modes of reception and groups of people; including HF, VHF/UHF IRLP & EchoLink, VHF & HF APRS, CWOP NOAA Program and ON-NHC Weather Observers Network.
(see our web site for more information on these programs): www.wx4nhc.org

WX4NHC is very proud to have maintained an active Amateur Radio Station at the National Hurricane Center for the past 30 years.

We appreciate all of the volunteers who help with our efforts.
